CARRIAGE r012. DRAG scnArnRsI' Application filed March 21,1921. "Serial No. $54,124.

To all whom itmay con-0cm;

Be it knownthat I, CLARENCE I. VRIGHT, a citizen of the United States. and resident of F airmead, in the county of Madera and the State of California, have invented a new and useful Improvement in Carriages for Drag Scrapers, of which the following; is a specification. H f

My invention relates to awheel attachment for a drag dirt scraper and means for guiding the scraper bowl for filling and dumping, its objectbeing to permit the person manipulating the scraper to easily direct the movements of the scraper bowl by turning a wheel adjacent to the seat in which the operator can ride. I accomplish this and other objects hereinafter set forth by means of the device illustrated in the accompanying drawings in which Figure 1 is a top view of the completed scraper and frame. Figure 2 shows the chain. and pulleys arranged for operating the scraper from the front end. Figure 3 is a side view of the device shown in Figure 1. Figure 4 is a sectional View of. the device along the line a2w' in Figure 3. Figure 5 is a separate view of the handle. Figure 6 is a front view of a pulley.

In said drawings C and C are main parallel longitudinal beams which are connected at the front end by a cross beam D. At the rear ends of beams C and C are inside projections E and E which carry'an axle F on which ground wheels B and B can rotate.

tach to a tractor pull. H and H are platform supports attached to beams C and C and extend backward therefrom. These supports carry a platform J at the rear of the wheels B and B Platform J carries an upright seat post K and a seat K attached to the top thereof, and also two posts L and L which support at the top a shaft M carrying a chain wheel M and a crank M by which crank the shaft M can be turned. On the top of the main beams C and C and adjacent to the front end thereof are upright posts N and N which are. connected at the top by a tie N At the rear of said beams, to wit, approximately at the location ofthe ground wheels are upright posts 0 and 0 A tie P connects posts N and O, and a tie P connects posts N and O at the top. In my drawings I have shown the posts 0 and (j integral with ties P and P although they G is a chain attached at one end to eachof the ends of cross beam D at its approximate center having a hook G to at may be formed separately and attached to gether. Q, and Q are supports for the scraper bowl. They are attached at the bottom to beams C and C They extend upward and the upper portion is bent atan';

angle and connected with tie's "P and P These supportsare located between posts 0 and N, and 0 and N R areadditional braces to support the platform J. S "is an ordinary sliding scraper; The form shown Specification of Lettcrs Patent. Patented hiarfl; 1922.

is what is commonly known as the Fresno scraper. shoes S and a rear handle S At the side ends of the scraper bowl S and S I have attached eyes S and S near the center of gravity of the bowl by which eyes the bowl is suspended from braces Q and Q by means It consists of a bowl S two front of chains S and S. S isa hitch consisting of two rods, one end ofieach rod being: pivoted to opposite sides of the bowl near the front, and the other ends being pivoted to V the cross'beam D. At the approximate cennoted that by turning the crank M the lever S willbe moved toward the front or toward the back, thus placing the. scraper bowl in position for filling, for carrying, or for dumping. The scraper bowl can'be given these different positions byv the operator while he remains on hisseat atthe rear of the platform by turning the Wheel M U is a shoe on the underside of the front end ofthe frame of the scraper to limit its downward movement and to make .it drag more easily when thefront end of the frame is lowered. It will be noted from the drawings that the posts N and N lean slightly forward, and toward the center of the frame, and the forward ends of ties P and P are closer together than the rear ends'ofth'ose ties, this construction tendingto strength to the truss construction.

-When the scraper isfloperated bya tractor the driver of the tractor can rotate wheel M*, which, in turn rotates chain wheel M atgive greater,

tached thereto, which moves chain T. This combination is inoperable unless the chain T is extended to chain wheel M as shown in Figure 2. Y and Y are adjustable supports for wheels M and M The double pulley T is aninterm'ediate support for chainT.

Having described my invention I claim as new and ask for Letters Patent: 7 v

1. In a device of the character described the combination of a base frame supported on wheels, having upright supports at the front and rear of the base frame connected with ties, a scraper bowl suspended from the upper portion of the supports, said scraper bowl having a handle extending upwardly attached to the back of the bowl, an endless chain carried on pulleys at the front, and at the rear of the frame, the upper end of said handle being attached to the chain, and independent means for rotating said pulleys at will, substantially as described.

2. A frame consisting of under beams, upper beams, and connecting posts, traction wheels adapted to carry the frame, a scraper bowl suspended within the frame by means of pliable supports attachedto the upper portion of the frame, means for tipping the,

scraper bowl consisting of a handle attached to the scraper bowl and extending upward, and means for moving the handle and the bowl consisting of an endless chain carried on pulleys, the upper end of the handle being attached to the chain so that it will move with the chain, and means for moving the chain at will by a crank, adapted to turn one of the pulleys carrying the chain.

3. In combination a frame carried on chain.
